Abstract

PURPOSE

This study aimed to report a case of peripapillary choroidal neovascularization (CNV) with a pitchfork sign.

CASE REPORT

A young female presented with a progressive and painless visual blurring of the left eye. Ophthalmoscopic findings and results of optical coherence tomography (OCT), OCT angiography (OCTA), and fluorescein angiography (FAG) were evaluated. OCT showed subretinal hyperreflective material adjacent to the optic nerve head with multiple vertical finger-like projections extending into the outer retina (pitchfork sign). OCTA revealed that seafan-shaped high-flow vessels above the retinal pigment epithelium (RPE) were compatible with CNV type 2 with a large feeder vessel completely contiguous with the optic nerve. No evidence of ocular or systemic inflammation was found.

CONCLUSION

Pitchfork sign can be seen in CNV type 2 in either inflammatory or noninflammatory conditions.

摘要

目的

本研究旨在报告一例伴有叉状征的视乳头周围脉络膜新生血管（CNV）病例。

病例报告

一名年轻女性出现左眼进行性无痛性视力模糊。评估了眼底镜检查结果以及光学相干断层扫描（OCT）、OCT血管造影（OCTA）和荧光素血管造影（FAG）的结果。OCT显示视神经乳头附近有视网膜下高反射物质，有多个垂直的指状突起延伸至外层视网膜（叉状征）。OCTA显示视网膜色素上皮（RPE）上方呈海扇状的高流量血管，符合2型CNV，有一条大的供血血管与视神经完全相连。未发现眼部或全身炎症的证据。

结论

在炎症性或非炎症性情况下，2型CNV中均可出现叉状征。
